Adult Health Nursing Study Guide Answers

Correct Answer: C

Rationale: The presentation described is consistent with fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, surrounded by a ring of inflammation. The filamentous opacities seen on slit-lamp examination are characteristic of fungal hyphae extending from the corneal lesion. This condition is often associated with risk factors such as trauma with vegetable matter, contact lens wear, or topical corticosteroid use. Prompt diagnosis and treatment with antifungal medications are essential to prevent complications and preserve vision.

Correct Answer: A

Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.

Correct Answer: C

Rationale: The correct advice to give to the owner of the dog in case of a dog bite is to feed the dog well and observe its behavior closely. It is not necessary to give away, impound, or kill the dog immediately after a bite incident. By feeding the dog well and observing its behavior, the owner can see if there are any underlying issues that may have caused the dog to bite. Additionally, observing the dog can help the owner determine if the dog has any health issues that need to be addressed. This approach allows the owner to make an informed decision about the dog's future while ensuring the safety of others.

Correct Answer: B

Rationale: In a pregnant woman presenting with severe abdominal pain and vaginal bleeding at 8 weeks gestation with a closed cervix, the most likely cause of these symptoms is a threatened abortion. A threatened abortion is a common complication of early pregnancy characterized by vaginal bleeding and lower abdominal pain without cervical dilation. The cervix remains closed, indicating that the pregnancy is still intact but at risk of potential miscarriage. Placenta previa typically presents with painless vaginal bleeding in the second or third trimester, whereas ectopic pregnancy usually presents with abdominal pain and vaginal bleeding in the setting of a closed cervix but is less likely at 8 weeks gestation. Gestational trophoblastic disease is a rare cause of vaginal bleeding in pregnancy and typically presents in the first trimester with signs of hyperemesis gravidarum, uterine enlargement, and elevated β-hCG levels.
